I won’t replace the belt yet.. im going to send the c/test back and borrow one from a friend.

As I say it was a project I’m a carer and am at home most of the time so to occupy my free time I’d thought I’d try and rebuild a car.. nothing more nothing less.. anyway I’ve stripped it down and the timing is all good, belt needs replacing but all good with timing.. im going to send the compression kit back as it is most likely faulty

Yes

Will investigate the engine further next week and will probably keep this thread updated.. im looking forward to figuring this one out and seeing where it takes me.. I spoke to an ecu guy that said he can get an ecu and do the programming etc at a reasonable price so I’m not overly concerned about that but I totally agree the engine needs looking into deeper was just trying to get a heads up on what to expect

No I could see the broken part on the filler cap n the part in the neck, no one put it there.. I understand what you guys are saying and I know the engine could be toast, but what are the chances it’s ecu as well?.

The car cost me nothing, I wanted a project over the next year to keep me busy so am not bothered about the time I put in..it’s very clean and has fsh with 100k on the clock. apart from the not starting and steering light on it’s a nice car. i can source an engine no problem and I’ve a found few under £400 but I’d really like to try and fix this. i haven’t checked timing yet etc but I will next week, like I say someone said ecu but I just felt the cranking wasn’t as strong as it should be

I found it strange also but I’ve never used this Amazon compression kit before so it could be rubbish n my other car is electric so cannot even test it.. I’ve had to remove the rocker cover because Some fool has over tightened the oil filler top and I found a bit of plastic sitting in the neck, I went to fish it out and dropped it.. there’s also an oil leak im trying to find as well under the hpfp, plugs look ok.. on cranking it sounds like low compression with that puff puff sound from the exhaust but again I’m not familiar with this engine. only engine fault on the diagnostic machine is air flow meter but I have that disconnected. the reason someone said ecu is because the previous owner clearly thought it didn’t start cos of faulty coil packs,they replaced the coil packs then gave up on it.. this car owes me nothing and im in no rush, just a project..

I put on a brand new battery as the old one was totally dead.. the faults do clear except steering light but I’m not concerned about that at this point..

Hi yes there is lights on dash when I run a diagnostic check it flags up these but like I say the compression test is o on all cylinders also I’ve checked wiring and fuse box etc replaced the ecm relay also I feel there’s 2 issues with this car,ecm n possible head gasket

Hi all bought an Audi a3 2L tfsi sline Quattro 55 plate as a project.. doesn’t start,cranking sounds like low compression so put my diag tool on it. only a few faults, 01314 & 01309 in brakes.. low battery terminal voltage in engine (replaced battery) so I did a compression test, the cheap Amazon kit was used, no compression on any cylinder. timing belt looks ok but haven’t checked the timing yet or the chain . I suspect head gasket but have very little knowledge on these engines.. as I say it’s a project and one I would like to repair.. any tips/advice would be appreciated (someone told me ecm/ecu is probably at fault but that won’t cause compression loss) tia

Hey been looking for a performance exhaust for a while for my 2005 a3 2.0 tfsi 5 dr Quattro but they are ridiculous money any suggestions on alternative fits?. i was just going to remove the resonator with a straight pipe but would prefer a back box tia
