Hi, I bought a mk4 R32 on Wednesday for my 32nd birthday lol. The engine management light is on and is throwing up a cam sensor code. My Mechanic is a mate of mine and he thinks it may need the chain doing. I called the garage that had been m.o.t ing it (a long way from the garage i bought it from). I was told it had an engine from a tt dropped in it 18 months ago. The chain was in good condition, it had a new water pump and clutch fitted ect.... They also said the light came on straight away and they had been unable to get it off. They recommended changing the tensioners. They told me the previous owner had really cared for her, and every time they had her in he would have a mini service done. Any help on this is much appreciated as my pal wants 700ish to change the chain. I realise that is quiet cheap for the job but an expense iI could do with out ha ha.
I believe Mk4 management running a newer engine (BUB) would throw that code. If the replacement engine still a BFH?
aye Ian the tt uses a newer timing setup than the mk4 r32 you hear lots of conflicting stories on this some say it works ok others say it throws a code worth checking the wiring to the sensors and solenoids are the right way round also worth getting it on vag com to see what readings you are getting if i'm honest i think you could have the same problem once the chain is swapped dose he still have the old engine ?
no problem ps welcome to the club BFH is the engine code should be on a sticker down next to the gearbox it's just under the vvt solenoids on the timing cover a mate of mine has a bora 4motion with a mk1 tt engine fitted though he has the tt ecu fitted as well
Just looked and its BUB pal. Do you think I'm best getting a tt ecu fitted then? Suppose it makes sense really lol
it all depends on what they swapped when they fitted the engine the BUB has a bigger maf and different injectors plus the mk2 tt has a different throttle pedal that thats different to the mk4 type so what ever way you go it's not going to be easy
yes but all you can find out is the year and maybe model it was fitted to the BUB was fitted to the mk5 r32 Audi TT and A3 from around 2005 on
so a bit of a nightmare lol. Do you know if you can get any info on the engine via its engine code? I know he had it fitted because it was low mileage
probably easier going thru all the sensors and swappable them for mk4 golf parts. I would imagine that most if not all the external stuff would have been swapped over from the old R32 lump, so the wiring loom plugged in etc. Hopefully in that case its just a case of change the tensioners for MK4 r32 items then the code should go, assuming thats possible?
On mine I have simply changed the plugs on the Mk4 loom to the ones from a Mk5 because they were different sizes. Not much help because mines a project car that isn't yet on the road. I know ACR Darlington knows about this and had swapped the cam sprockets on another car. You should be able to find them on Facebook or try and PM a user on here called 'Andyout'
Aye Ian mine has the the different smaller plugs Need to get my finger out and get the loom and ECU fitted
aye i looked into this with the late BUB engine you need the timing cover the two sensors plus the two solenoids and housing/timing case and the adjusters for the cams new your speaking early BUB engines may need less parts as they have the solenoids with the larger plugs
I wonder if you can flash the mk5 r32 firmware to the mk4 ecu, if possible id buy a later 2.8 ECU to try this on as I know those can be flashed with mk4 r32 firmware. then its just a case of does it still output the revo signal and have the vss inputs like the mk4 has, or if all of that is turned off in firmware. If those both still work then this could be an easy way to run mk5 r32 engines in mk1-3... for a mk4 I guess the revo wont be an issue as the clocks read it from canbus anyway, assumign signal is the same etc. but not sure if the vss signal is available on the canbus for the mk5 ecu to pickup?
BFH hardware bits would need to be swapped back, or all BUB bits will need to be present, including the ECU. John, no you cannot flash software that is not compatible with the ECUs drivers or architecture.
