GTI issues what to do

[Sharkie]

Has anyone any experience of these aftermarket all alloy w-pump/thermostats, currently advertised on Facebook (Sydney)? Priced at $500 or $1000 fitted. Not sure of brand or where they are made - probably China.

Thats for a mk6 GTI lads, EA888.1

Genuine pump and thermostats are $1,150 + labour takes it up to $1,650 ish.

There are also a couple more Facebook ads from apparently different sellers in Sydney region, but not clear which EA888 engine series these will fit.

My 2015 GTI has both direct injection and port injection = no carbon buildup. Does yours have both?

Cylinder 2 misfire, hopefully/possibly just a failing coil pack or spark plug. Easy cheap fix if either of those.

As for the air leak, check all your hose clamps and see if there are any obvious wear/holes in your intake pipes.

Some thoughts on this.

Today I replaced the inlet manifold on 2017 Polo GTI (1800 EA888.3) with both port and direct injection. Incidentally it is exactly the same motor as MK7 Golf GTI with only 2 differences being an IS12 instead of IS20 turbo and a different crankshaft giving 1800cc instead of 2000cc (rounded).

The inlets in the head had quite a bit of carbon build up at only 49000km ..... Since it was open already, I cleaned it but was amazed at what it looked like. Alas, did not stop to take any photos though.
