- Diesel woes!
Had the car in the garage for a cam belt change, 2010 Mundaneo, 150k. The car was running perfectly well previously and upto it going into the garage.
After getting it back it misfires when cold. Revs to about 2500rpm then misfires, splutters. After it has warmed up it’s all good.
They had it back and said it was because I had let it go low on fuel, fine it has been low on fuel and it is 6 years old, 150k miles but the filter should sort that. Also said they fixed it with a flush etc but as I drove off it was exactly the same.
I am letting them have it this week to get it fixed and they say they will get a diesel specialist to look at it! But they keep changing their tune from dirty fuel to fuel injector issue.
Was fine before it went in and I am not buying it as coincidental that it is now misfiring?
What are my options? Hope they fix it and drive off with a cheery wave saying they broke it they can stick their bill up their a%&e! Suck it and pay? Get a report and go legal! I have no idea how much it will be or what the issue is but giving them an opportunity to fix seems fair!
Have thought of bombers, wee in shoes and hoof in slats.Posted 3 years agotrail_ratMember
talking utter pish about the low fuel/injectors thing …especially as it goes away when warmed up
could be a multitude of things though.
I reckon they have dismantled a bunch of stuff to get at the cam belt and may have disturbed a sensor (ive not worked on a mondano diesel before – so im speculating) but things that make those symptoms for me in the past – dead or dying MAF or timing fuel pump advance could be out by a fraction (depending on the tensioner set up)
Has anyone run PROPER diagnostics on it ? – and i dont mean a 9.99 ebay job i mean a propper unit that can be trusted……Posted 3 years ago
Ok so the collective seems to think the bill should fall to the garage! ALso it should be a relatively easy fix! Just wish they did it right first time! Bit pee’d off back and forth.
Hopefully they fix it and when they call while away and start tell me it needs ABC I can just collect and drive off 😀Posted 3 years agoalanlMember
No, it’s unlikely to be the belt a tooth out, as it would happen all the time. More likely to be, as stated above, a sensor has been disturbed, hence giving a rough running when cold. Mass air flow sensor would be my first call, possibly the fuel injectors need a clean (fuel additive).Posted 3 years ago
Is it coming up with any codes? Though you probably havent got a reader.swedishmattMember
My cars diesel injectors died at 125k. I was rationalising it got better when warm, better quality diesel etc etc. But really, it was past it. It spluttered and misfired and then diesel injector specialist confirmed the four injectors were shot and leaking diesel into the engine or some such and not operating properly. check your oil.levels, if above max it could be putting diesel into the oil levels…Posted 3 years agotomasoSubscriber
If you get a diagnostic read out of the codes it will tell you what the problems are. However, it takes someone with some understanding of the system to interpret what it really means.
Cheapest fix is the crank sensor that gets covered in disintegrated dual mass flywheel pieces. Take it out remove metal from magnet/sensor and put it back in.
It is a bit rum if it went in fine and comes out with a misfire after they have serviced it.Posted 3 years agoflee5Subscriber
Is it a 1.8 diesel. If so has the garage done both the timing belts as the second belt is a wet belt on that year and many small garages don’t even know it’s there. The second belt is the one that runs the injector pump so if it’s not been changed or timed up wrong could be causing injector type issues.Posted 3 years agoflee5Subscriber
I know of at least two local garages who have changed the main belt on 1.8d fords only to have the car brought back on a trailer within a week when the wet belt has destroyed itself.I think it was supposed to be a longer life belt when originally fit but the service schedule has been reduced bease of problems mainly the teeth rotting off the belts.Posted 3 years ago
