    Volksy got a reaction from SiC in Benzin' (I want to get off Mr Benz Wild Ride)   
    I’m still deep in the throws of KE-Jetronic insanity. The S Class has steadily been getting worse and worse.
     
    I had a mobile classic car tuning specialist out to have a look at it the other week. He was recommended by my local Bosch Specialist* 
    We put it on an Exhaust gas analyser to get a measure of how it was running. Badly was the answer. I knew it was running rich, given the wallet raping fuel consumption. So we dialled the mixture back to within a tolerable spec. 
    Essentially I bought the last year of this model that did not come fitted with an O2 sensor, Those with an O2 sensor have a ‘Duty Cycle’ which can be read from the diagnostic port with a multimeter, which is a kinda basic code reader, different percentages suggest which parts of the system are faulty. 
    On mine the fuel mixture is controlled as the engine warms up by monitoring the water temperature rather than the exhaust gases, so there is no ‘Duty Cycle’ to monitor, only the CO level in the exhaust. This means that aside from measuring the specs of each individual component of the FI System (of which there are many) and ensuring that you do not have even the slightest vacuum leak the system, it is notoriously hard to diagnose. To set this non duty cycle system up, it can only be done on an exhaust analyser, tinkering with it without any form of reference will potentially brick the system.
    So how did it drive with the mixture set correctly? Terribly. No power, the gearbox did not know what to do with itself, it was continually cutting out etc etc. F*cksticks.
     
    The car is now really starting to try my patience, and as I discussed with the tuning guy, cars with KE-Jetronic fall into an expertise black hole. Essentially they are too new (and complex) for the classic repair/tuning community to want to get involved or understand how to repair or deal with them. Any modern garage has the same issue, those techies who did know how to deal with KE have now retired/died/been sectioned.
    My neighbour used to run a Bosch centre many moons ago, and for a bottle of wine took a gander over the car. We have found what could be a vacuum leak from the rubber ‘boot’ that attaches the injection unit to the inlet manifold, so I now have one awaiting to be fitted this coming weekend. This means stripping off the FI system, then splitting the base off the fuel distributor as the boot is clamped between the lower and upper halves, which to be honest is a somewhat daunting task. 
    The theory being that the vacuum leak has been there for a while, and a previous owner has tinkered with the mixture (which should only be adjusted as a last resort - Mercedes put caps and seals on those adjustments for a genuine reason - mine have all been removed) to try and adjust around the fault(s). 
    Mr. Imp has an Exhaust Analyser thankfully that I can borrow, so hopefully once the system is air tight, I can set the mixture to the correct level. Whether this will stop the random cutting out that I have experienced since owning the car, as the vacuum/mixture system is of course connected to the ignition system, remains to be seen.
    These also have a reputation of burning through alternator voltage regulators, which also can cause mystery issues. Essentially the slightest fluctuation in charging voltage sends the prehistoric electronics into panic. This is regulated by the OVP relay (covered earlier in this thread) which, if detecting a spike, cuts power to the ECU’s causing no end of running issues. These can happen so quickly that the charging system doesn’t even register that there is an issue, so won’t illuminate the dash light. In fact the ABS system is the first to register that there is some shenanigans going on, and will throw that light on instead. I have noticed that on the odd occasion it has thrown the ABS lamp, especially if I’ve given it a bootful to try and clear its throat so to speak. A new one for the alternator was £20, so that will be fitted on the weekend also. 

    There is a particularly nasty looking 300SE being broken on Faecesbook down in Nottingham, but attempts to get the seller to let me know what he wants for parts off it have come to no fruition. He’s said I can come and remove the bits, but not how much he wants for them. The idea was to purchase the Fi System for a source of spares.

    Well, let's see how the weekend goes…….

    Volksy got a reaction from Minimad5 in Benzin' (I want to get off Mr Benz Wild Ride)   
    The £79 Autodoc one arrived today, I'll post a photo of it when I get home, as I dropped it and the car off at home earlier. 
    Its interesting, as it seems to be made of a solid piece of Alloy rather than a bendy metal plate covering. It's the red top double fuse one, as with you, I had been told that it simply supersedes the single fuse one which are NLA. 
    As I was tinkering with it the other day, my neighbour came out for a nosey. I know he's a semi retired Private Jet pilot, but what I didn't realise is that he also ran a Bosch Centre. He explained all the workings of the FI system, then casually mentioned that he has all the special tools etc to recalibrate the KE - Jetronic system fitted to mine. 
    So I WILL be taking him up on the offer of a tune up once the OVP is fitted!

    So how did it drive with the mixture set correctly? Terribly. No power, the gearbox did not know what to do with itself, it was continually cutting out etc etc. F*cksticks.
     
    The car is now really starting to try my patience, and as I discussed with the tuning guy, cars with KE-Jetronic fall into an expertise black hole. Essentially they are too new (and complex) for the classic repair/tuning community to want to get involved or understand how to repair or deal with them. Any modern garage has the same issue, those techies who did know how to deal with KE have now retired/died/been sectioned.
    My neighbour used to run a Bosch centre many moons ago, and for a bottle of wine took a gander over the car. We have found what could be a vacuum leak from the rubber ‘boot’ that attaches the injection unit to the inlet manifold, so I now have one awaiting to be fitted this coming weekend. This means stripping off the FI system, then splitting the base off the fuel distributor as the boot is clamped between the lower and upper halves, which to be honest is a somewhat daunting task. 
    The theory being that the vacuum leak has been there for a while, and a previous owner has tinkered with the mixture (which should only be adjusted as a last resort - Mercedes put caps and seals on those adjustments for a genuine reason - mine have all been removed) to try and adjust around the fault(s). 
    Mr. Imp has an Exhaust Analyser thankfully that I can borrow, so hopefully once the system is air tight, I can set the mixture to the correct level. Whether this will stop the random cutting out that I have experienced since owning the car, as the vacuum/mixture system is of course connected to the ignition system, remains to be seen.
    These also have a reputation of burning through alternator voltage regulators, which also can cause mystery issues. Essentially the slightest fluctuation in charging voltage sends the prehistoric electronics into panic. This is regulated by the OVP relay (covered earlier in this thread) which, if detecting a spike, cuts power to the ECU’s causing no end of running issues. These can happen so quickly that the charging system doesn’t even register that there is an issue, so won’t illuminate the dash light. In fact the ABS system is the first to register that there is some shenanigans going on, and will throw that light on instead. I have noticed that on the odd occasion it has thrown the ABS lamp, especially if I’ve given it a bootful to try and clear its throat so to speak. A new one for the alternator was £20, so that will be fitted on the weekend also. 

    There is a particularly nasty looking 300SE being broken on Faecesbook down in Nottingham, but attempts to get the seller to let me know what he wants for parts off it have come to no fruition. He’s said I can come and remove the bits, but not how much he wants for them. The idea was to purchase the Fi System for a source of spares.

    Well, let's see how the weekend goes…….

    I’m still deep in the throws of KE-Jetronic insanity. The S Class has steadily been getting worse and worse.
     
    I had a mobile classic car tuning specialist out to have a look at it the other week. He was recommended by my local Bosch Specialist* 
    We put it on an Exhaust gas analyser to get a measure of how it was running. Badly was the answer. I knew it was running rich, given the wallet raping fuel consumption. So we dialled the mixture back to within a tolerable spec. 
    Essentially I bought the last year of this model that did not come fitted with an O2 sensor, Those with an O2 sensor have a ‘Duty Cycle’ which can be read from the diagnostic port with a multimeter, which is a kinda basic code reader, different percentages suggest which parts of the system are faulty. 
    On mine the fuel mixture is controlled as the engine warms up by monitoring the water temperature rather than the exhaust gases, so there is no ‘Duty Cycle’ to monitor, only the CO level in the exhaust. This means that aside from measuring the specs of each individual component of the FI System (of which there are many) and ensuring that you do not have even the slightest vacuum leak the system, it is notoriously hard to diagnose. To set this non duty cycle system up, it can only be done on an exhaust analyser, tinkering with it without any form of reference will potentially brick the system.

    I nearly sent one of those little trailers into space a few years back, it was unladen on the back of my 4x4 so couldn’t be seen or felt.
    I momentarily forgot myself and went over one of those narrow speed bumps without slowing down as the 4x4 wheels could pass either side of it.
    The trailer then immediately made itself seen and felt, as its wheels could not pass either side 😬 I thought it was coming through the back window and absolutely shit myself, I’ve not made that mistake again.

    We have these all over Leeds. Generally running in the central reservation of dual carriageways or designated lanes. They run by two small guide wheels attached to the front hubs which run against the raised kerbs to provide steering/guidance for the busses. 
    They do work in Leeds, as it takes the bus out of the traffic system gives priority at key junctions etc.

    Being lucky enough to grow up partially in Spain, Seats have always been part of our extended family. 
    My dad bought a new 1988 Ibiza 1.2L in black (E185PUG) from AMG Porsche in Leeds. We kept it about three years, with it not missing a beat. It did plenty of trips down to the east coast of Spain, It was a rocker switchgear early model and he loved it. It got me kudos on the school pick up as it had systemPORSCHE stickers on the lower parts of the doors (in the correct Porsche font too..).
    It was replaced with a 1990 1.2XL in metallic blue (G998KWX) bought new from a garage in York. This was after VW had started to take control, so had the VW Polo/Golf switchgear.  This one was not so good, it overheated a few times, had autochoke issues and bits of trim were dropping off left right and centre, it was traded in for a Peugeot 106.
    On the subject of Malagas, I think N.Bickle has a 5dr (Malaga/Ronda) but I think the last UK one expired several years ago (a grey XL facelift). I spotted it in a battered state at my local Morrisons, I assume to the owner it was just an car, and didn't know it's unicorn status. I spotted a few weeks later at CoPart York, having had an attempted theft and what looked like a carb fire. It was for sale complete, but I think it was thrown in the frag due to lack of interest.
