I was going to stick it on the bay for £130 (what i paid for it). £100 for members on here though. Otherwise it will join the growing P38 parts bin. Your welcome to try it first to see if your ECU is the problem.How cheap is your ECU if I do end up needing one ?!

Thats very kind of you mate, I shall bear it in mind. I'm going to try and do a bit of testing first as its basically free. First job is to remove my ECU and look for any water ingress or damage to the pins. I'll try and slip over to dads one afternoon and get a meter on it.
At the risk of lazyness, is there anything to stop me leaving the sensors connected and testing to see if there is a difference on the meter between the rear right (working apparently) and rear left? As surely they should offer the same results if they both work. If they both offer the same that absolves the wiring and sensors?

No problem.
I can't see an issue with leaving the sensors connected to test them. Just thought if you could remove them easily enough you could swap rear right to rear left to see if the fault follows. Easier said than done though as i had to drill out my front right sensor after 13 years of rust taken hold

I do have a slight other problem now with removing wheels at the moment, dear old dad trying to help the other day didnt get the locking wheel nut on square and stood on the brace and has managed to snap a pin out of the locking wheel nut tool and damage the wheel nut so I'm awaiting delivery of a set new lockers to replace them... It never rains! Will do my diagnostics hopefully over the next couple of days and keep you posted!

Who mentioned cheap?
Imagine my disappointment when seeing loads of old type ECU's on the bay for £15 - £30, then realising it was changed to the new one from '99 & nearly 10 times the price.

Be happy you are not buying a new 2 wheel traction control unit. SRD100501 4 wheel traction control ECU £856.68. ANR4898 2 wheel traction control ECU £1191.89.

Rimmer brothers. They are the only two versions still available.

2 wheel TC ANR4898 cheap as chips on eBay. Anything 4 wheel SRD100290 SRD100500 or SRD100501. A bit pricey.
That's why i was looking on the bay.Be happy you are not buying a new 2 wheel traction control unit. SRD100501 4 wheel traction control ECU £856.68. ANR4898 2 wheel traction control ECU £1191.89.

Just to be clear, you've tested the sensor for resistance and you've checked continuity from the connector that goes into the ECU and the sensor and all is good?
Not yet, that's on the to do list! I need to get a few minutes in the day light when it isnt raining to do some further testing.

You had better move South, Wammers and I had a drink on the patio today, I was in my budgie smugglers and he was in his mankini. Mozz didn't turn up in his thong, he said it was to hot for him.
To be fair its been a nice day! I managed to get 5 minutes to fit my replacement sat nav computer. However, family duties called and we decided to go for a walk and then to the shops with out little 5 month old. I was also "working" - overtime to feed the P38's thirst for bits!You had better move South, Wammers and I had a drink on the patio today, I was in my budgie smugglers and he was in his mankini.

Lovely down here. I even saw that strange orange burny thing in the sky a few days ago.

OK. Finally got a few minutes to nip out the with the meter. I decided to go for the jugular and pulled C505 from the ABS ecu and tested pins 3+6 and 7+8 one gave me 898ohms and the other 937ohms. I also tested my "spare" wabco sensor which also showed me about 900 cant just remember of the top of my head.
The pins in the connector and in the ecu looked clean as a whistle and could have been fitted yesterday. (In all fairness I was expecting it to be damp and corroded etc) so I think that shows that the sensors and the wiring is all intact and functioning as intended. I've got in touch with a chap I know with a very similar P38 (my old one actually) and hes happy for me to try his ECU to see what happens and if that improves things.
Fingers crossed!
