Sooo. Just looking for a few opinions really. Back in March (yes March...6months later & around 20 visits to two separate garages it's still not sorted :mad:) 4 lights came on. ABS/TC & two others. Went to garage for plug in. Faulty front wheel sensor. Repaired with replica part. Lights still came on. Replaced with genuine Vauxhall part just in case my car was rejecting the replica. Fault cleared. Lights came on again along with the immobiliser light which I'm told are not related whatsoever. However they ALWAYS come on together. Plugged in again and now showing fault with back wheel sensor. Full hub replaced for this. In the meantime my car had been in & out of a Vauxhall specialist garage re the immobiliser light who changed my key & batteries. Still the light comes on. Now again all the 4 lights have returned. Latest plug in and showed the original fault from back in March which was the front sensor issue, which my garage said will need to replace the hub as the front only had a sensor not the full hub like the back one. But that front wheel sensor fault has only returned after 6 months and now my breaks are jittering again like back in March. I'm just spending money on repairs and nothing being resolved and would like some professional opinions. Sorry so long hopefully makes sense!!!!!

Total, sick of seeing fault lights and spending money with it not been fixed. Unfortunately not no It's been plugged in at least ten times between the garages (fortunately free of charge apart from the first time by each garage).

Hull. I've done a lot of googling tonight after just having enough of it!! And it seems it has happened to a few Mirevas. My local garage said it could be the ECU for which I'd have to take back to Evan Halshaw as they were the Vauxhall specialists dealing with the immobiliser fault light. But then with the jittery break it makes me think it has to be the sensors. Just worried if I pay out more money next weekend for this new full hub then are the lights just gonna be on again the next day like they have kept doing!!

They really need to do some live data to see what the sensors are doing, this combined with a code read should give them a clue as to whats wrong and which circuit is playing up, they should then do some tests on the wiring to make sure its not water getting into the plug for the sensor and the wires not shorting to ground somewhere...i wouldnt be surprised if the wiring for the sensor you had replaced in March has chaffed through somewhere because they never clipped it back correctly, it would also explain why it lasted for a few months before returning...

I wouldnt have anymore repairs done to the Immo system until this fault is sorted as it may be related in some way..i know the Meriva has a weird door locking system (Flex Door) which may be effected by the incorrect speed signal.

Thank you I appreciate that advice. Luckily I haven't been paying at Evan Halshaw re the immobiliser. Only the £50 plug in charge initially. I've always said they seem to be linked but shut down and said it's impossible for them to be. My local garage has been doing the wheel sensor repairs. And is booked in next Sat for him to fit the new hub to the front. He said he would do the labour for free so just for me to pay £100 the part. Which I'd be fine with if this was the end of it but I just have a bad feeling and can't afford to pay anything more after that as that will be a £450 total!!! I will show him that message (even though he may take offence I've seeked a second opinion ). Yes it does have different doors!!

At the moment when I break it shudders and my speedometer goes up and down and on two occasions it's effected my radio volume. This happened back in March when I had the first repair. Since then up until last two weeks it's drove Perfect despite all the lights showing.

The problem your experiencing does suggest its a speed sensor thats at fault, to confirm this the garage would need to do some live data on the front speed sensors and there related wiring, its the best advice i can give, i think you've had a bad experience with the garage, maybe you should try someone else.

The tough thing is I've used them for 7 years and I feel I have to be loyal and stay with them as they've also been good to me ha. Well I do appreciate your help as at least I know the problem definitely is with the sensors and if and when they do get sorted hopefully the immobiliser light (which only shows occasionally) will disappear and if not it will be back to the Vauxhall specialist with that. One more question. Can my local garage run this ?live data or is this some specialist kind of test. Thanks again.

Lol..you will be fine, you could also ask if the speed sensors are handed, if they aint then they could swap the 2 front speed sensors over and see if the fault moves to the other wheel, if it dont then you know its either the hub or a wiring fault, if it does then the sensor is faulty again.

This is a strange one for the same fault to come back so quickly after new hubs being fitted. I'd be checking the way they install it and the wiring as I know the front looms can cause problems even after replacing both front hubs (going by the known fault on the Astra G /Zafira A not sure if this is the same problem as you have). It's all to do with the age and twist and turns the wire route takes in the engine bay and wheel arch. Opcom for the codes/live data and a multimeter to check the wires. Worse case possible the abs ecu.

It's been a total nightmare to be honest. Because he put an off marker sensor on initially and the lights still came on he thought it was that so once he put the genuine on it cleared until now. Then the back one went so he just put the off market hub in. So far that code has cleared for back and only front one showing. Do you think it's worth me paying the £100 for this hub replacement at the front? Is it quite common for both wheel sensors to go together? I wondered as well why with the front one he replaced wheel sensor but with the back one the full hub!?

Oh that makes sense then thank you as I did wonder that. I will request that he does a bit more testing before replacing the hub to make sure. And hopefully once both new hubs are in place it will be the end of it and the immobiliser light will dissappear (positive thinking). Just strange how the front sensor fault code had cleared for 6 months once the sensor was fitted and the jittering break resolved.

If it has abs system fitted all the hubs should have the sensors. If a normal hub (No sensor ) has been fitted there's your problem. It could be a coincidence that it's the opposite hub that has failed. But codes or live data should pinpoint which sensor is at fault best to find that out rather than throw money at it by changing the same part. When both my front sensors failed I never had the jittery brakes. After replacing both front senssors the fault code was still there so then moved on to the abs ecu then the wiring been code free for a few years now . Not sure if the zafira A system is the same as fitted to yours but worth looking further/ investigating the cause of it.

They replaced the full back hub as Andy confirmed that's what it comes as. But the front one. Same side of car. They just replaced the sensor not the full hub. So is booked in for the full hub replacing on Saturday. Garage has agreed to do labour for free so I just pay the part. I just have a bad feeling it won't be the end of it.
