DSC Sensor Interchangeability face-lift/preface-lift 3452 6769174

Post by Chrisd928 » Sat Dec 21, 2019 7:14 pm

Edit Solved:
The prefacelift dsc sensor part no 34526764018 does work on a facelift E86. Way cheaper than the facelift part number 3452 6769174. This sensor throws error code 5E38. hope this helps someone with the dreaded 'trifecta' of tcs, tyre warning and handrake lit in yellow.



Hi guys,

I Had the trifecta of lights on the dash (dsc, handbrake and pad warning) all in orange.
I read the codes (dis V57) and got 5E38 which is the dsc sensor located under the drivers seat, as well as others for wheel speed sensor etc which are now all sorted, (full new knuckle, hub and sensor etc) . I have removed the unit and the part number is 3452 6769174-03, these seem rare as only fitted to face lift E85/E86.
The earlier pre face-lift unit is part no 34526764018 which real oem seems to say is exchangeable retrospectively, but it doesn't seem to be the same in reverse, or am I reading it wrong?

Can anyone tell me if the pre Face-lift version will work on a face-lift E86? plenty of the earlier part around but later one seems rare and expensive (£230 to send away for repair, £550 ish new).

Alternatively if anyone has one going for a fair price then that would be great!

Thanks in Advance for any input

I have a facelift version that I could be willing to let go for the right price.

You can’t fit a pre facelift one I wouldn’t think.

I’ll send you a pm.

Fantastic, thank you! I did order a pre face-lift one a few days back on the off-chance it would work. If it doesn't then I'll post it up on here for free collection/postage cost

but either way I'm definitely interested in the correct part, please do drop me a message to discuss price and postage etc.
Thanks Srhutch!

I’ll pm you but you’d probably be better off getting yours repaired as it’s the usual issue you have.

thanks srhutch, appreciate the advice, its only reading code 5e38 (sensor issue) and i have cycled the pump with Inpa, but i agree they do seem a common failure. i'm not to far from the place in Heanor that does it so guess its worth taking off and dropping into them for test/repair. Need to get the ccv and valve seals done as well, currently have soot on the tail pipes, black spark plugs (1yr and 3k miles old Bosch oem) and white smoke from exhaust. Just to top it off the fans sounding like its about to self destruct so need to grab a new one of those as well (£400 cheapest so far!)

have you not tried fitting the pre-factlift version and using SSS v32 to code the new module, it will ask you for the part numbers of both the old unit and the new one. Can't see why it wouldn't work

Hi Neil, i've just done exactly that, prefacelift sensor arrived this morning, but didn't need to code it. cheapest i could get old sensor rebuilt was £230, one from prefacelift off ebay cost £25! Pump wasnt throwing any codes (most common failiure) so was fairly certain it was the sensor. I did calibrate the old one using dis v57, but the lights stayed on and code was constant.
Just need a radiator fan now, like rocking horse poo to find! Got the ccv and alternator belts and pulleys to do and then its back on the road!

Little confused now, what was the sensor at £25?

The sensor for £25 was the prefaclift dsc sensor mate, plug and play compatible with a face-lift car. It's the other way by the looks of it they aren't compatible (post face-lift sensor in a prefacelift car).
Can finally get it through an mot now all lights are off :D

No, the speed sensor is different to the dsc(yaw and acelleration) sensor. The part I replaced was the dsc sensor under the drivers seat. Cost £25 off ebay, part number 34526764018, the face-lift version part no. 3452 6769174 is rare and expensive but the prefacelift one works just fine. I already did the 2 front wheel speed sensors when I rebuilt the hub/knuckle etc. Code 5e38 is the code I had which relates to the yaw sensor not the abs pump or wheel speed sensor. (all tested with inpa and dis v57).
