ECU tune impact on warranty
#21
Please re-read the OP's question. It's not 'will the engine go bang' or 'will the tune be effective', it's simply 'will the warranty pay'.
The answer is no. The fact that it's leased car makes things even more complicated. There's probably a clause that prohibits doing a mod in the first place.
The answer is no. The fact that it's leased car makes things even more complicated. There's probably a clause that prohibits doing a mod in the first place.
1. The oil service interval was stated at 15,000 miles and consumption was found to be higher than expected.
2. The electronic dipstick was not functioning correctly and did not provide low oil warning or limp mode activation.
Consequently a number of engines ran their main bearings. I had one customer at the time who had a pulley & tune, and another acquaintance who had a pulley & tune from Paramount. Both engines were replaced under warranty.
More recently, we helped a gentleman who had previously installed a VMax tune, and who had his cam phasers fail, to get his OEM software back onto the car. His engine was subsequently replaced under warranty, despite having the software trace in place for a non-original calibration.
So, practically speaking my experience has been that if you have a 'known' issue; meaning something which JLR has experienced in the past, with reasonable frequency as a known failure item, then you will most likely not have too much trouble. For example, the timing chain tensioner is not an uncommon failure item on these engines. It's far from being endemic but we hear of a few. So if you present with this issue, most likely it will simply be approved as it is already on the radar.
However, if you come in with a rod through the side of the block, all bets are off. And, certainly I agree with you that it is prudent to err on the side of caution and take the worst case assumption just in case.
Worth remembering something on these V6 engines - this is the same block as the V8, which is making 575BHP in factory trim. Like, it literally is a V8, with the rear 2 bores blanked off in the crank-case, counterweights on the crank etc.
So all of the FEAD system, much of the drivetrain components etc. etc. are comfortably handling nearly 600BHP, in factory spec.

Yeah, I may go that direction if I'm not happy with the rennchip. I didn't want to flash the ECU just yet. I know you get slightly better results but it stays on the ECU logs. I'm not trying to deceive my dealer but the piggyback can come off like it was never there. Sort of taking the easy route first, plus I can always sell it and get some money back.

I am pretty sure this is not correct, every tune to the car is traceable, regardless if you can piggyback to original file. You can do the same with Stuart's tune. Engineer will always be able to tell if you modified anything if they want to look for it. I never heard of a mod that would not leave a trace other then maybe replacing a certain part and then going back to original? I might not be understanding the tune you are talking about though.

They would be able to see that, not that every time they would look but if they did they could see it and chances are if there is an engine failure, they will look at the logs. In the past I would also flash back to stock when going in for service. Some dealers are cool with things, you'd have to feel it out. Bottom line though, from a procedure standpoint on the warranty, they may need to read out the ECU. Flashing is going to show up as an event.

As the OP for this thread my question was if certain dealers were more or less aggressive about looking for ECU modifications and how they might apply their concern to warranty issues. 3 or so years ago Audi had most of their dealers actively checking the ECU and flagged the vehicle. It does not seem Jaguar has taken this approach. Of course if there is serious engine failure there will be much greater risk. i have done an ECU mod on multiple Audi's , a Saab and a MB and never had an issue. My VelocityAP programmer is on the way.

Short answers;
- The dealer techs do not have to search for it, if they are reading codes in the car for any reason, they will be presented with the code for the "non-OEM calibration".
- Every single time a car with the "non-OEM calibration" code is connected to the dealers diagnostic system, the session is sent back to JLR HQ as a priority.
JLR are not "looking" for it, they have an automated system in place that takes care of that.
Whether or not they care about your car having a tune in it is a different question, but they do know if it has been tuned.
The dealer won't care either way as long as he's being paid, either by the vehicle owner or by JLR.
If your tuned car goes in for a warranty claim for a failed water pump, I don't think they will care. If it goes in for a warranty claim with a conrod poking out the side of the block, I'd say you're in trouble...

That said, theoretically they could deny a claim for any number of spurious reasons. Some manufacturers state that warranties are invalidated by track use for example.

We would evaluate on a case by case basis. Thus far after 10 years in the business we haven't had an 'warranty' issue to date, so to speak. If we were responsible for something which was caused by the tune we would stand behind it 100%.
