What Have They Done To My Car?

[TeamGreen]

Hi everyone,

 

just had the cambelt changed on my 98 Sharan 110TDI AFN and since then the engine is very hard to start when cold especially in the morning. The glowplug light goes out pretty much straight away as though the engine is warm but takes an absolute age to start and when it does there is a great cloud of smoke so the fuel must be getting through ok. Is there anything that thy might have done to cause this or is it pure coincidence? Prior to going in there were no probs at all.

 

Once the car is running then everything is fine with ecconomy of between 40mpg and 50mpg so it must be ok otherwise. It goes back to them next week but any suggestions / ideas would be greatly appreciated as I am worried that they may hit me with a bill that they might have caused.

 

Cheers.

perhaps the belt is 1 tooth out now, hence the crap starting. take it back and demand they put it right

Does sound like the timing is out. Had the same thing happen to me, twice! First time when I had a recon engine fitted, then when I had a new fuel pump fitted.

Thanks for replying so quickly guys, it's always good to go back in a situation like this armed with a good idea as to what the problem is so that they can't give you a load of bull.

 

Cheers.

just had my cambelt fitted last week and when i got it back it was driviving flat ,no power at all.......rand fords today and spoke to the manager and he said that if it was one tooth out it would not start at all........he thinks its the air flow sensor in my case so he is taking the car back today to have a look........till tell him that it went in ok and come out rubbish and that i was going to recall the money back through the bank until sorted.....lol

IIRC the sprockets are not keyed on a Mk1 and the correct procedure is to lock the camshaft and pump sprocket in predetermined precise positions and the top sprocket is removed to change the belt. If they have been sloppy then the timing can be out by any amount even a fraction of a tooth.

 

That is almost certainly what has happened.

Timing timing timing had the same issue some time ago with another garage thankfully they put it right , i also wouldn't pay them a penny untill they put it right ! :23:
