I've ran a gt sport 170 for 2 years and it's never missed a beat,the only real is problems with some of them is DPF issues.

DPF regeneration issues can be a problem if you do a lot of short journeys. The DPF has been known to block completely and choke the car - or worse.

You can of course get the DPF removed and then with a remap you are looking at around 210bhp and 300lbft.  :cool:

R-Tech are offering this service for £500 i thinks.

I think there's an injector recall on a certain run of models. You can tell if it needs the recall by checking some number, maybe on the injector? Sorry I don't have more details but a friend of mine was telling me about it.

Its not an official recall but the 170 injectors are known to fail.  Mate of mine has just had his replaced FOC but it took a couple of weeks to get VW to admit there is a fault.

I had mine done back in August  :smiley:

As per Rhyso mentions injectors go wrong. Rhyso and me both got ours replaced FOC.

That's the lovely DPF pipe for you  :sad:  I'm averaging high 40's over the course of a tank

do you drive everywhere downhill?  :huh:  and have you worked out your REAL MPG i.e. from tank to tank rather than relying on the computer

Considering the poor ecconony, DPF and injector issues, my money would go on a newer 140 and a cheeky remap.

The only visual difference between the 140 and 170 is the exhaust. A lower vallance and a Milltek will soon address that issue it it would bother you.
