Try what, hitting with hammer, disconnecting it? Sorry for lack of background knowledge!

Also I've just read off similar issues being down to failing EGR, is this a possibility?

Expand  

No, don’t hit it with a hammer it’s only plastic. Swap it with another one. The EGR on these rarely coke up in practice, it’s a bit of a twat to remove completely. You can see if it’s starting to fill by taking off the top metal hose that runs over the cylinder head and looking inside. 

As above though the on/off nature when it’s cold is a trait I think but the code for the turbo solenoid would also suggest there’s an issue there.

OK thanks. 

The on off nature was when it was hot anyway. 

OK thanks I'll swap the solenoid 😊looking in the EGR seems sensible as a precaution.

I thought the point of the egr was partly to aid warm up?

The commute the car goes on starts with 15 mins down hill in the cold air so it doesn't get up to temperature on cooler days until its traveled 6 or 7 miles so wouldn’t blocking the system off increase engine wear? I mean it's done 240,000 miles so I don't think increased engine wear is a desirable thing to have. 

[junkyarddog]

They are just an emission reduction device,but in reality they just help gum up the engine at this age and mileage. 

It's a simple job to blank off,if you find it makes a difference to the cars oil dilution problem then leave it in,if not it's simple to remove the blank again.

It's worth a try,it also improves acceleration slightly when taking off from standstill.

The good news with that particular Mondeo is that because it was registered before July 2008, the EML being on is not an MOT fail.

Its in with the garage for boost solenoid as it needs to do weekend nights and of course with a light on its not regenerating so it's got dilute oil, so it needs doing and I'm busy and the family vomiting everywhere currently so there's sfa chance of me doing in time. 

[Cord Fourteener]

Also, she's done several thousand miles, never complained about the car so it's doing well, it will be good to get the boost control sorted if it needs it. 

214,455 it's on, not 240,000 as I said earlier.

Did you tell them ‘some men on the internet told me...’ 🤣

Anyone got any ideas? Dodgy boost control solenoid, sticky turbo vanes? Or wires starting to go in a sensor or something?

Think you need to buy a replacement car, it sounds fucked to me!

I might buy a replacement car but not for this mondeo...

I've always dreamed of owning two mondeos. No wait, that was a nightmare...

Hopefully it’ll settle down and behave itself now!

The Nightmare on Privat Drive or the solenoid?

Lol but seriously, hopefully. Absolutely everything else seems to have been fixed according to the history apart from some trailing arms so fingers crossed...

Well the cluster switched off while driving today and I lost indicators.

Looks like the cluster refurb is now an immediate priority.

Before you do that, plug the ELM427 in, next time it craps out try switching it between the CANBUS switch, sometimes that will identify if there is an issue with the BCM module, also put it through Forscan, potential damp/corrosion in the BCM needs to be ruled out before spaffing £200 on a recon dash.

Thank for the advice but I don't have forscan or ability to switch canbus using elm.

Gonna have to hope its cluster and if not, then worry about BCM.

Although will check BCM for any obvious signs of damp and corrosion.

ELM427 adapter is £14 on eBay then free download of Forscan. Without that your ability to accurately diagnose faults etc is significantly curtailed unless you’ve some fairly high end software. 

Although these recon places have a rig to test the equipment on they’re not infallible. I had a cluster repaired and it turned out it wasn’t the actual fault but they still turned round and said ‘faulty cluster’ we’ve rebuilt it you!

I need to clarify.

I don't have a laptop to run forscan.

I could get forscan lite for android. Unsure if the lite version would do the job.

Hitting dashboard does resolve issue. Which suggests its the cluster.

Car owes me little. Bout 100 quid more than I get back from bridge.

Have to think carefully about spending boatload, that might not fix issue and losing a lot of money.

Just south of Bath. I agree with @sierraman. It needs code reading before I throw money at it.

I will find a garage locally. My usual place does not really do moderns like this.

Thats a very generous offer, but don't want to risk your goodies getting nicked in the post.

If I can't get it sorted locally, I may have to drive to you, without speedo, rev counter, fuel gauge or indicators.

Sat nav and hand signals should get me there though lol

You'll be welcome for definite if you do make it here!

Just don't expect me to know a lot, but definitely willng to plug in and push buttons, so to speak. 

Let's hope that doesn't get quoted out of context 😅

[sierraman]

The cluster takes minutes to remove, in all honesty you are as well reading it yourself. A lot of garages like to run you round the houses so to speak, they’ve no idea what it is but they’ll rinse you for £50-60 to send you in the wrong direction.

So the plan to get the Mondeo in the garage and out again before Wifey's work today didn't quite go to plan. 

Garage say its not the solenoid, there's a boost leak somewhere but they've not found it. 

Also they say there's a crack in the sump. They are getting a revised quote together so the Mondeo is staying with the garage... and it begins. 

So Wifey is away in the Passat and I'm doing family long haul in the Volvo 740 who leaks coolant into the foot well.

Knock the lamp out on Forscan, reset values. If it’s running ok then I’d worry about it come MOT time. 

My philosophy with these things is that if some bad stuff was going off it’d run like shit.
