My A4 1.9 tdi has lost power at the >50 mph end, overtaking is a chore. I have been told that the injectors need replacing. The car has done 160,000 miles (I bought at 130,000) so not sure if they have ever been changed. A local injector specialist is quoting £250 +VAT to refurbish, but I can buy them online for £70 + VAT each.

Does anyone know if it a difficult job to replace them and if specialist tools are required?

Many thanks

 

We in the US must refer to our European Brothas. We are not worthy of Diesel Audis. They don't sell them here!

 

I dont know about on the Audi motor but on other diesels I have worked on the injectors were not to bad at all to get to and get out, I doubt there are any special tools but i dont know for sure

 

very simple job mate as are the glow plugs "all on top of the engine"

 

Thanks all for your help. I think i'll give it a go.

I have another small challenge, that of the stuck on hot heating. i have seen a few postings about a flap motor valve but i'm not sure where is is located. any ideas?

Thanks
