Hi Just had cam belt changed on my 2.0 hdi engine which was done by a friends friend in is own workshop car runs find but runs flat no turbo boost ? i have had air meter part in airfilter box changed but still no turbo any ideas as he seems at a lose what it could be . could the timing on the belt be out time any help would be great

I think if you look at the situation logically, if all was well before the cam belt change then there must be something wrong, like the valve timing being a tooth out.

Go back and get them to check it out.

can the belt be checked with out stripping down is it a visual thing i could see

[jasper5]

Sorry, but you would have to get as far as taking the timing belt covers off and checking the timing or at least the top cover off and fitting a pin through the timing hole in the flywheel., then checking if the cam pulley hole is in the correct position ( about 8 o' clock).

Could it be that vacume pipes to the turbo actuator have been desturbed ?

I would first check all hoses to the turbo,& intercooler if you have one.I had the belt changed on my Xantia TD a few years ago.All was well untill 2 miles from the garage,i put my foot down & nothing.Found the intercooler hose clip not tightend,& the hose had come off.
Have also had this myself,forgetting to tighten a turbo hose up,& having no power

thanks

Dont no if i am barking up the wrong tree but i have disconnected the mass air valve connector no differance to way car is running still lacks power would this be the problem as the car is running fine ! but with no turbo boost

I think I'd take jasper's advice and get your mate's mate to give it a drive!

Had the same issue when I had my timing belt (and water pump and aux belt) replaced ... well ... as it's all on the same side may as well hit all 3 in one go! Turned out the grease monkey had pulled a vacuum pipe off at the rear of the engine ... took the b*gger 6 days to sort it though!!!!!!!!

[jasper5]

If you called me a grease monkey you would wait 6 months.
Accidents happen, it's easy to pull off a pipe and not know, but to be fair, he should have looked straight away.

[beatlebacker]

No offence intended Jasper ... I only refer the term to incompetent mechs ... none such on this site.

[jasper5]

No problem, i'm just an over-sensitive old git, been in the job 40 years and hate being referred to as a grease monkey ....don't mind being called an old git

Dunno if this show itself up as a by product of a vac leak but...If a vac pipe is off or leaking would you feel it on the brakes too... ie although working they would need a little more pressure and less bite? As there would be reduced vacuum at the servo.Just a thought on where to look to narrow it down a little?
