last week the heater stopped working....only now blowing warmish air?
and now....the traction control light has come on aswell as the abs light is on, the speedo has stopped working and the power steering has become really heavy.....really strange this has all happened at the same time....
HELP.....!!!!!!!....please :-/
-
checked your fuses? ::)
-
please fix your avatar >:(
-
i will have a look at the fuses in the mornning.... but my wife first noticed the problem earlyer today but she said it only lasted about 20 mins then went back to normal....! i went to go to the shop a little while ago and as soon as i started the car the problem was there...?
sorry about the avatar.....!!! oppsss....sorted now ;)

Hi Nick....your ABS/TC ECU is knackered mate...replace it and you will get your power steering back, your speedo back and the lights will go out...you can get it repaired...or you can get one from a same year same model same gearbox type car...
Heater on the other hand may be lowon gas if aircon??
-
that sounds expensive.....?
mines a 3.0 MV6 facelift on a V plate....
any ideas where i'd pick one up from...?
Nick
:y
-
heater.....is climate control....
when set to cold will blow cold.... i know it's winter but i think it's working on cold....?
i do get a "coolant low" message now and again.... i top it up, run the engine with the filler cap off to get rid of any air locks.... or am i doing it wrong?
cheers
Nick

If your losing coolant and aircon isnt running right then quite possibly HBV (heater bypass valve) is leaking...
Repairing ECU about £100 or so I believe...as you have a facelift might be worth getting it fixed as may be hard finding a replacement I guess...its an awkward job to do but doable yourself, about 2 or 3 hours of fiddling if its your first time doing it, very frustrating as its just a matter of removing the 6 screws to remove the ECU!! :)
-
hope its not the HBV.....i changed this last year.....and nearly broke my wrist getting to the valve.....!!!
i dont notice any leaks on the floor....?
any idea where i'd send or take my ecu for repair?
cheers
:y
-
is there a way of testing the ecu when it's still in the car?....
not that i'm saying your wrong.....i'd like to know for certain before i start ripping the motor apart......!!!!!!!1
oh....bugger.....!

as your in hayes, isnt there a place near the airport that break omegas etc? you might get lucky & get one from them, i think they sell stuff on fleabay as well, either way there are specialist breakers on fleabay for miggys so might be worth using the "email the seller" option to enquire ;)
-
bba reman top of the list via google for abs ecu recon.
Check the hbv is not wet or showing residue for the coolent leak. If not your into the v of the engine for oil cooler cover plate, stat housing, or coolent bridge. It you still cant find the leak then try the metal coolent pipe at the back of the block above the bell housing or core plugs in cylinder head around the back by dis pac.
No personal experience of the heater issue but would suggest checking the vacume pipes in engine bay. Esp the elbow on top of the hbv itself as this operates the heater vents i beleive. Guide in maintenance section for vac pipes.

Sold gsxr. It was crap, and old to be fair. Got a blade now, it works.

hi, nick, i cant find out exactly where the miggy breakers are but the phone number is,,,,,0770 6495877,,,,,,but they do say they are near heathrow airport, hope this helps :y
-
Place near Thiefrow is omegaspareparts - 0770 6495877. Done some bis with them on ebay and they were very good. Don't know where they got that title from.
Fredsta ;) :) ;D >:( :( :o 8-) ::) :P (Whatever - humbug humbug humburger)

thanks chaps....i'll give them a call in the mornning....
funny thing is the lights have gone out, the speedo is working and the power steering working again.....!!!!!
would a faulty abs/tc ecu act in this way? work intermitainly???
topped the water up this mornning and the heater is still rubbish....
i changed the HBV about three years ago...... surely it would last longer then that?
N
-
so....if i have to get the old one out (ecu) and the new one in, is there a "how to" on he forum somewhere....?
N
-
to what ive read on here yes they do tend to act that way before totally gooing fubar, so best get it done before that fateful day! ;)

When my ABS ECU on the old car played up it was almost predictably intermittent, would work fine from cold for about 30-40 minutes then fail for about 20 minutes then work ok from then on. If you then stopped and switched off for any reason ... on restart it would not work for about 2 hours when it would suddenly start to work ok again.
BBA-Reman sorted it on a 5 day turn around for £130 .. but this was a couple of years ago .. :)

Yes, they can be intermittent
I have looked at a number of failed units now and they have ALL failed in the same way!
The units are constructed as two separate section.
At the connector block end is the power side with the two main relays and a number of diodes.
At the back of the actuator coils (12 on V6 and TC variants, 8 on 4 pots and non TC variants) is a hybrid circuit board with a number of components and two 'glob and gloop' IC's.
This hybrid is wired to the main contacts in the plastic block using standard IC bond wires.
What happens is that there appears to be a main feed to the hybrid which has two bond wires to it.....these wires break at the point where they make contact with the main contact with the main block.
I am looking at options for repair of this for those with a steady hand.
Given the above, you can imagine that the connection could well be intermittent and even heat dependent

thanks again chaps... i had a mate just come round and he put his tech 2 on and found that there is no communication with the ecu.....= knackered....like you all said, i just had to make sure.... you know how it is...!!
so all i need to do is get the right ecu....? are they all the same for my model?..... anyone have a part number? my mate has a few in his garage (he works on saabs) and apparently they sometimes use the same parts......
if he has one and i get to keep the knackered one i may have go at repairing it..... ala previous post..... and offer it out to other members..

Ideally you need part no off old ecu, as there are a few variants
-
My ABS ECU on my 2.5L year 2000 facelift auto was Bosch part number 0273004206 (Vx 9117171). I got mine from I think a late minifacelift from a breaker. About £40 some 3 years ago I think. If you go to your local Vx dealer, he will quote you about £300 but he will also be able to tell you the Bosch and Vx part numbers. As others have said, there are a few variants.
It did take some finding though so you might be better off having your own reconditioned
-
cheers for that.... i'll give Vauxhall a call in the mornning for a "price" and ask for the part numbers..... just to check against my one on the car.... ;)
-
right......just called vauxhall and got the part number for the abs ecu.... from my chassis numbers
i couldn't find the number on mine...(it's still in the car...)
Vaux: 9117171
bosch: 12730004206
now the hunt for one....!
-
At least you know an ABS unit from any V6 within a year of two of yours will likely fit
-
just remembered.....heater top hose going into heater matrix....very hot... bottom hose coming out....not very hot... just warm....?
is it hbv?
-
matrix blockage? did you get a result with it yet
