Would it be a big job to replace the wiring loom from the MAF to the ECU? Where does the ecu live on the 2.5TDi? If it's in the engine bay, could be an easy job?
Finding someone willing to provide an ECU for testing purposes is almost impossible. As with any elctronics, once it's been plugged in, who knows what's happened to it. I wouldn't feel comfortable putting someone else's working ECU into my faulty car, there is a possibility that whatever caused...
So I've got the car back, it's not fixed. They had the car for about 10 days and they've spent over 15 hours on it. The great news is that they haven't charged me a penny! It's the 1st car in their 6 years that has defeated them. It's got another new MAF, the engine timing has been corrected...
The car is still with Awesome, they have arranged for an expert to have a look at the car on Monday, but I'm assuming they have checked for leaking hoses or blockages?! I've already asked them to check the EGR solenoid valve as that has been highlighted as a possible cause. They are the experts...
Murran, thanks for the offer, I'm a good few miles from sheffield, but if awesome don't diagnose it with their freelance specialist on Monday, I may just take u up on your offer. I'm running out of ideas now. What would happen if I ran the car with the MAF unplugged? It runs well with it...
Yeah, everybody wants a go at this, money for nothing, hours and hours of headscratching and guesswork at £50 odd per hour (excl VAT!). Gone are the days of getting results for ur money!
Specialist rang today, he suspects the timing is out. Is it possible for modern ecu controlled cars to drift out of timing or is that only possible if the belt has jumped a tooth? If so, why is it ok when the MAF is unplugged? How do you check the timing, is it done through vag-com? I'm worried...
Don't feel bad everyone, even the experts are stumped with this one. Everything is fine when the MAF is disconnected, but she runs like a dog even with several new MAF's. I can't see the dealership finding the fault if the vag specialists can't.
Anyone know the dangers of running with the MAF...
Can't see any point in putting a 3rd MAF in, what are the chances of both new MAF's being faulty? They showed me the laptop which was displaying the requested air flow and the attained air flow. At idle, it was requesting 170ish, and attained was 170, so all fine. Increase the revs until the...
Just popped into Awesome on the off-chance they could run a diagnostic. They've pulled the car in, no fault codes! Mech recons it's a duff MAF! He's gonna get a new one and pop it in, watch this space.
