Polo GTI 2012 jerking as it changes up in gear, i have checked and there are misfires showing, ive done compression tests all fine, cylinder air leak tests all fine, the only thing i haven't checked is the fuel injectors. Its not throwing any codes too vagcom at all and im not sure if i can check the values of the injectors. Could it be anything else? There is no eml light nor any smoking.

Polo 6R GTI is always a CAVE or CTHE engine (the notorious twincharged 1.4 TSI) with a DQ200 7-speed DSG. It never came with a manual gearbox.

Not quite .... VW made running changes to the hardware and software fitted so it's important to know the details of the modules fitted to your Polo.

It may even be that there is a software update that could help, but without an Auto-Scan we can't advise you :cool:

Readiness indicates faults have been cleared from the ECU recently. What faults were there?

have you checked the dogbone mount and engine mounts? could be a mechanical issue. the 1.4Tsi is notorious for misfires. the remedy was everything from revised shorter spark plugs, to revised injectors to software updates and even new pistons as the original ones would break at the piston ring lands

Switched and swapped spark plugs, completed compression tests, checked for leaks, only thing that is left is fuel injectors, I will be trying an injector cleaner before new injectors, what sort of software updates are you thinking is it on the ecu?

, what sort of software updates are you thinking is it on the ecu?

the 1.4Tsi dual charge had loads of software updates, they dealt with misfires when cold, they reduced the power slightly to keep detonation at bay and thusprotect the pistons from the earlier mentioned cracks etc... make sure they software is upto date on both the engine and gearbox as well. 0AM 7 speed also had loads of updates.

Would the broken engine mount/ gearbox mount cause misfiring?


no but it woulde cause the Jerks on shifting. also maybe check if any of the internal CV joints are worn as well. excessive play on them would cause the jerk you describe on shifting

Does this engine have a tune or is it fully standard?

The mechanic suspects fuel injectors but i just would expect a code. The engine has never been tuned i had this check it has its stock file on.

How would i check the software updates?
A preliminary check can be done here:

You have 9970. There's a 9971 too.
