Hi
I have a service light problem for past 9 months (from 44K km) and now the car has clocked around 60K km. Till now the car goes to TASS and come back with "Try now sir" response from TASS. I am posting here as I could not find similar problem in other posts. Though I see few service light problems I see them reproducable with certain sequence of actions (say coasting from 80Kmph etc..). Please let me know if there is a post/reply for such a problem. Current problem:
The service light indicator will glow (when car is idle or while slowing down for a speed breaker) and go off after few minutes. Maximum time it has glowed was for 5mins. History:
This problem started after a water wash underhood in TASS.
Immediate problem observed after water wash - the fluctuation of rpm around/below idle rpm and TASS folks that time mentioned that it is because of engine coldness and this fluctuation would go off after some time.
But it did not go off. Along with this problem, I got "service light" errors for
1) High pressure / low pressure circuit error
2) Accelerator sensor error
First couple of times these errors were reset from ECU and I was told the error was rectified by cleaning sensor and connections.
(side note: One of the TASS employee was arguing with me that -low pressure line is the one from diesel tank to diesel filter and the high pressure line is the one from filter to pump :-( . I had to take a lesson to him what is what :-()
As these errors repeated (first one in highways & second error in low speed/idle) along with cold start fluctuation, I forced them for a resolutions. After lot of talks and lot of service time/delays - one injector was replaced and car was sent back to me.
But still I had all the problems and the car was sent again to TASS and they replaced all the injectors. Now this solved the "service light" indication of "high pressure & low pressure circuit" error" & cold start rpm fluctuation. But still I was getting "service light" for "accelerator sensor" error.
After couple of months again cold start fluctuation error came. I was also fighting with TASS for my "service light" problem that time. TML engineer took up the car this time and replaced the Mass flow sensor and now the cold start problem went away. But still the service light (for accelerator sensor) remains and this is the current pendinig problem.
Each of the service light indications are not hard (does not always continue to glow or reproducable) but were recorded in ECU.
Though the TASS/TML sorted out the "high pressure/low pressure circuit error" problem noting it from ECU, now they refuse to sort out the second problem saying that it is not reproducable for them at workshop. As per my knowledge they did not change any part to solve this problem not even accelerator pedal/sensor.
They convince me that this is a "no harm" problem and ask me to use the car. I am fighting with them
1) for a proper fix with root cause analysis
2) or a undertaking letter saying that this is known design problem and could not be fixed as of now & that will undertake the services free of cost for any problems arising out of this
3) or a undertaking letter saying that they could not diagonise the problem and they will service any engine problem free of cost.
Right now the car in service for past 11 days and even now I am being asked (by TML CSM/TASS) to take back the vehicle saying (verbally) that (1) they could not reproduce the problem (even though the problem is recorded in ECU) and that (2) they will help me in future issues.
I have gone through lot of mental pressures in these episodes (which is happening for past 1 year almost) and tensionful discussion. I had not described them above. Also I have not mentioned n number of service pickup and drops happened to solve this problem in vain.
Please let me know if anyone has got similar problem.
Kindly help me by suggesting
1) if you have come across this problem and if there is any know fix for this issue
2)What are the options for me at this point to handle TASS/TML. Please note that I was notified that the issue is logged in TML database.
Thank you
Vichu
