I'm praying you are right on that one Pepste.r
My VSA light started coming on intermittently round about last year in October, an gradually came on more frequently. Then in April the ABS light also started appearing and eventully both remained 'on' despite restarting the engine. So one afternoon last month I dropped in to Peterborough Honda and spoke to a chap at the service desk and explained the problem.
He said that the once the car started showing these lights, it would need a new VSA/ABS module. I argued the it could be one of the sensors. He then offered to have a technician run a diagnostic (without charge) as he didn't want me to "pay" for what he had already told me!! After a short period he returned and said that I had been right, it was the rear right side sensor. So I booked the car in to replace the sensor.
On the day, I dropped off the car and returned about 2hrs later and it was ready. However after picking up the car, I drove about 5 miles around town then the VSA light came back on (with no ABS light), & going 'on' a short while after restarting. I called the garage and they asked to return the car - which I did and they promptly checked it over again. This time he said that this could happen after replacing a sensor, however some 'new software' had been uploaded and should sort out the problem- if not, it would need a new module. I took the car again and this time it managed 20miles before the VSA light came back on. Yep, I was ****ed off. So last week I dropped in again and spoke to the same chap at the service desk, and this time he stood firm and said there would be no point looking at the car again as it would definitely be the module, and said "You could even change all the sensors and it won't make a difference." I still insisted it could be the sensor, perhaps not fitted properly?? Frustrated, I then left not entirely convinced that I got a fair deal, and not really looking forward to coughing up over 1k for a new part as I'm looking to change cars in a years time.
I'm wondering why the initial diagnostic only picked up the sensor fault , but NOT the module?? Did they fit the sensor properly?? Also, why did the follow up diagnostic then show a possible fault with the module?? So right now I'm not sure how I'm gonna sort this out. The car is now on 115k and has been very reliable over the past five years, but this is now kinda spoiling my love for it.
I seriously doubt the VSA module on a petrol will ever fail .. it will be a wheel sensor more like the left rear wheel.
