[Resolved]  Maruti Ritz — trying to Cheat

RNS Motors, Hosur Road, Bangalore -
Left my Ritz VDI for 20000Kms 4th paid service. The Dealer billed me for performing D/E (Explained to me as Decarbonising Engine) for an additional labour amount of Rs.1750/- plus Tax. On questioning the nature of work carried out by D/E, i got vague repies viz - head decarbonising, turbo and exhaust manifold opening and decarbonising - etc. At 20000Kms , with no performance complaints by the user, i suspected i was being taken for a ride. When i told the service advisor that this amount would be paid by me only after consulting Maruti Company personnel , after half an hour, the bill was recast without D /E, for Rs.2000/- less, and the Car delivered to me.

As a Maruti owner, I am pained that a reputed dealer like RNS motors has actually instructed their personnel to overcharge their customers for fictitous and unecessary work claimed to be carried out.
Being in the Diesel Generator service field myself, I was able to question the nature of D/E and escape being cheated!!! What about your average customer????

Please correct me if i am wrong, but i fail to see how a 20000kms old DDIS engine needs a decarbonisation, and the vehicle was ready in 6 hours flat with all the oil changes / filters changes / car washing / and D/E carried out?? Also if the engine was opened, for what reason?, and how was it refitted without head gaskets, other manifold gaskets being changed???
