Audi 80tdi sewing machine

[simyboye]

Hi there, hope your all well?

I have recently bought a audi 80tdi avant. Although when running either from cold or when warm sounds like a sewing machine. I appreciate its probably hydraulic tappets, but can they be adjusted, or are they just shot? Car runs fine. Just sounds terrible!

Also, anyone know what these tdi tuning boxes are like? Any good?

Thanks
James

Welcome to the forum.

Hydraulic tappets can't be adjusted so maybe time to replace them. (Mines just started to sound like its 'knocking' so maybe due for a set of lifters, sounds awful when its cold!).

Don't know anything about tuning boxes except that I want one although I'm going to hold off on that mod until someone quotes me a decent price for one. Got quoted £250+VAT the other day.....rip off.

The alternative is to chip the ecu which can be tuned properly from a laptop inside the car on the road. This is by far the best (but more expensive) option.
