I got car delivered on saturday. tata motors representative was there at concord motors. they have replaced evaporator,expansion valve and turbo as per bill. I took a test drive in the afternoon(the car was parked absorbing heat) and as expected AC was not satisfactory. but, SA claimed they(CRM,Tata rep and him) did the test drive without putting dashboard and cooling was fine. so, after 5 minutes they returned the car(blower air throw area was obstructed by some cushioning material.)
next took the TD for around 40 minutes and AC was cooling OK but not comparable to the cooling we get used to in competitor class hatchbacks like swift or ritz which IMO
have chiller AC's.
anyways, for the back row passengers, now can sit without sweating even though cooling is not extremely satisfactory. then, that is what these models(2008-9-10) with small compressor can achieve. I pressed for a compressor replacement under extended warranty with tata rep. and he is reluctant claiming that "Sir, our cars can only bring down 10 degrees from ambient temperature". ridiculous! he acknowledged that there is a issue with Vistas of earlier lot whose AC cooling is not adequate.(He CATEGORICALLY denied this after few hours).
I tried explaining to these fellows why should I bear the issue of a defective/inadequate AC which fails to cool enough in the noon-afternoon time? newer models may have a better compressor as per what I heard.
but, after complaining with Tata motors customercare, the work done this time was good enough. they replaced turbo and some other parts. Concorde charged only Rs914 after all this.
Tata representative took another 3 hours connecting laptop fixing some AC parameters though we have to wait.
overall, satisfactory. but, I will still want to have a newer compressor honouring warranty which IMO
is justifiable. SA otoh is a very nice guy and he later told me, newer vistas are much better especially power steering and other parts. just that being loyal to tata we the first owners of Vista are bound to get trouble because - tata takes its own time experimenting and fixing their cars!
so - Tata knows that Vista's AC is not sufficient enough especially with earlier models. they are not ready to replace compressors.
had it been with other tata dealer/service in ernakulam/muvattupuzha, I am sure it is not going to be such a smooth sail.
I will want to have compressor replaced if possible. It costs Rs36000 or so with TASS to refit a new one!
