Stevey ive tried doing with vcds but keeps coming up with not running any ideas pal 

Thanks 

Thanks Stevey 

well had the timing chain and head rebuilt after the timing chain failed

got the call to pick up my car when i arrived at the garage the mechanic told me the eml light has come on due to the o2 sensors going bad 

so I've changed both o2 sensors for new genuine bosh sensors and the fault codes are still there can anybody shed any light on my problem please 

The engines are very similar to the s3 engine which is a cdl engine code would it not fit

Many thanks Adam. Looks well worth spending on, and hope it finds an appropriate home soon.

Kind regards,

Gareth. 

Would be worth putting a second engine or having a engine rebuild adam best part of 6500 to replace

Hi much as I hate to say this but it sounds from the videos like the timing has slipped, I think from memory these engines have a chain, it sounds as though when the coil packs are connected it is firing back through an open valve which may account for the rapid sooting of the other components down the line it may have gone round one tooth which won't kill it but it won't do it any favours either, how many miles has it done? I know the manufacturers say the chain should last the life of the car but that won't take into account extra wear caused by extended service interval oil degradation.

Steve.

130000 thousand miles i take it the one tooth wouldn't kill the valves but would throw  the timing out Steve

Ive put a couple of videos on Steven first one has the coil packs disconnected sound sweet has a nut turning over 

Second video its trying to start but sounds like a can of nits and bolts are in the rocker cover

Whats happened the timing chain let go 

thanks Steve 

I've disconnected the fuel line to the fuel rail there's fuel there I've took the plugs out and cranked it you can see them firing away if i start the engine with the  plugs in it sounds like its running on two cylinders then cuts out if a disconnect the coil packs it spins over like it should do I've changed the crank sensor for another replacement to see if that des the trick I've  also checked the voltage to crank sensor cam sensor and coil packs I've got a healthy spark its definitely something or nothing will keep you posted got to be timing related 

thanks paul

Hi it would help if you had some codes, not sure on petrol models but on my diesel there is a crank sensor adaptation protocol which has to be re adapted when fitting the new part, it sounds more of a fuel pressure problem but that would throw a code up, only other thing I can think of is try the old crank sensor again as if it starts on that one it may be the new one is defective.

Steve.

Ive ordered another crank sensor ive scanned it with delpgi and vcds no codes im going to check the values again and reset the adaptions on the ecu and try again will check the fuel pressure any ideas what it should be stevey in positive its something or nothing thanks again 

where do i start lol

car had a slight misfire scanned the car cam sensor so i thought change that which i did know the car wont start so checked the following

changed crank sensor 

checked voltage to crank cam and coil packs

checked chain visually and on vcds its saying bank 1   specific 28 degrees

                                                                             bank 1   actual 28 degrees

                                                                             bank 1  phase 0 degrees 

which i understand is correct   

the car has a spark but looks weak in my opinion

done a compression test 195 psi on all 4 cylinders 

car cranks starts making a chugging noise then dies pulled the plugs out plus bank one o2 sensor and there carboned up straight away there are no fault codes mechanic cant look at the car while next week as anyone any idea where i can look next thanks in advance paul
