Lost 40bhp somewhere...

[the.buried]

Hi, been a long time lurker and usually found answers to my questions without having to post (or even join to be fair) but I’m a bit stuck.

Bought my 2005 A4 Avant B7 in June. It’s a 2.0tdi with 130k Miles and has always felt underpowered compared to my A3(2.0tdi) but I put it down to it being a bigger car. I had problems with the EGR (now been deleted) which I assumed was the main cause but and it’s been better but I’ve had it on the rolling road this morning and it’s running 99bhp.

There’s no lights on the dash, no discernible noises and I get that older cars usually lose some power over time but 40bhp seems quite a bit!

Anybody else had similar problems or get any recommendations as to where to start looking?

Any attention to the dodgy oil pump drive ?

Not looked at it to be honest...is it a common problem for these?

just to add to my original post, it feels most under powered below 2k revs in first and second gear. Once the turbo kicks in it’s ok (ish)

Yes serious issue .

Double issue BLB by any chance ?

Sorry bud, not sure what you mean?

BLB engine code ?

Have a look at the intake manifold see if that’s full of carbon build up/oil

slight boost leaks

turbo vains, make sure fully free and moving easily

Get it remapped, my pd140 always felt sluggish, getting it mapped helped a lot

thanks...I’ll have look (it was remapped while on the Dyno . Up to 130 now but still want my other 40)
