2011 BlueMotion 1.2 TDI - Down on Power (?)

Post by Vaguely Competent »

Hi all, I just picked up a lovely white 2011 Polo, it seems to have been well looked after, got a decent service history etc, although it is a little wounded after someone drove into it near at a McDonalds :roll:, whatever, just need to replace the bumper and realign the bonnet a bit.

My concern is that in low revs the engine is an absoulte bag of ***** some of the time, it's been a good 12+ years since I drove anything with an engine this small, but the only thing I can compare it to is the 1.8 Non Turbo Diesel Ford Escort, I had back in the dark ages.

Looking at the specs on Parkers, it has a comparible engine to the '98 1.4 Golf I had for 5+ years, but low end it just doesn't compare, pulling away it sometimes feels like I'm in 3rd not 1st, same with changing gears, I tried changing when it recommended eg. 3^ change to 4, and I'd get a noticable drop in power and speed increase until rpm was at 3k+

Is this normal? I remember Clarkson called this model absoultely gutless among other things in the race to blackpool episode :lol:

My only thought is that the check engine light has recently pinged on for P0405 (Exhaust Gas Recirculation Sensor A Circuit Low) and maybe I should hit that with a hammer?

P0405 is indeed a good reason it's down on power. Even more. Is the glow plug light blinking?

Ah excellent, I shall retrieve my hammer. No other warning lights on at all.

Looking at youtube videos the egr is in a far more inconvient location on the 1.2 than the 1.4, ehhhh, I'm guessing pull it out and give the valve a good clean is the advice going forward or have I got the wrong end of the stick entirely?

It often goes wrong without the option of saving it. The cooler either starts to leak or the valve/potentiometer will be fubar
