In december I remember the workshop person giving me a 10-12k estimate and now suddenly it’s 30k.
Bhpian shrvenkataraman recently shared this with other enthusiasts:
Got a Tiago BS4 2020 Jan, XZ version.
Recently got engine light symbol for a while and Tata showroom reset it
It turned on again and they checked and they are saying it’s a catalytic converter failure and that replacement would cost 30k+ and that they have to order the part.
Is this right? Do catcons fail in under 50k kms? And do they cost this much for Tiago? In december I remember the workshop person saying 10-12k estimate and now suddenly it’s 30k.
Car is at tata techwheels workshop in Jaipur sitapura. They are saying it will take 5-6 days for part to arrive.
What are the odds of catcon failure under 50k km of mileage? And how do I find out what the actual cost of catcon is – and if Tata is not having me overpay for it?
They said they’ll have to keep the car for 5-6 days, i asked for it back until part arrives. They returned the car with 3 scratches below headlight.
They basically mentioned that as a policy Tata doesn’t repair catcons because repair only means cleaning of the catalytic converter and if the cleaning is not thorough and even small amount of dirt or impurities remain inside that it will cause fault again.
They mentioned that it may be done aftermarket and that I’d have to contact someone who does it aftermarket, but even if it is done, there’s a high risk of failure again. So they advise me to go for brand new catcon.
I am not a car guy, a software engineer here. So, I don’t really understand these things and I try to read about all this. Not sure what’s the next step here other than to wait for the catcon part arrival.
This was the error code diagnostic that they shared.
Here’s what Bhpian Suhaas307 had to say on the matter:
Catalytic converters are generally very expensive, since they are packed with several precious metals such as palladium, rhodium, etc.
Normally, it is expected to cost upwards of 50k. Not sure what Tata charges for a replacement cat-con but I do not expect it to be cheap at all.
Please check with multiple dealers / authorised service centres.
Failure in 5 years / 15,000 km could be considered premature. You must press your dealership / authorised service centre to replace it at their cost or at a discounted rate at the very least.
Here’s what BHPIAN GARYTI had to say on the matter:
CatCon failure under 50k kms seems very strange, almost impossible dare I say. Catalytic Converters can easily last over 10-15 years and upwards of 2 lakh kms if maintained properly. I would advise you to check this with another Tata Service Centre or an FNG to get various opinions and ensure it has been properly diagnosed.
The problem may lie with a faulty O2 sensor which is more known and prone to such issues hence the Check Engine Light, either way, it’s easier and more cost-effective to rule out the smaller possibilities rather than jumping to an expensive solution that isn’t even certain to fix the error.
