I am hoping to get some definitive advice in relation to the hydraulic pipes supplying the active anti roll bar.

As detailed in a seperate post I had to have the vehicle recovered to supplying MD due to a oil leak in the pipework.

Vehicle is covered by 2 years approved warranty and I am trying to prepare my evidence in case they try and decline to pay for the work.

Vehicle first registered Jan 2018. Full service history by LR main dealer.

Bought by me Nov 2024 with 79000 miles - currently 80000 miles.
Last MOT at 77400 miles April 2024 with no advisories.

From other posts I think they will try and decline on 'fair wear and tear' or 'corrosion' not being covered.

Having looked at the MOT test manual significant corrosion in the antiroll bar/suspension is a major fault and should result in a fail.

My argument is that if there was significant corrosion it should have at least been an advisory and if there was nothing to concern the MOT inspector then I can reasonably claim this is an unexpected failure and have my claim honoured.

As this is a static part it is difficult to see where 'wear and tear' would apply.

Any observations would be gratefully received. L405 2018 5.0 S/C

Last year my 2017MY failed its MOT on corroded ARC pipes (no fluid leaks). In 2023, the previous MOT, there was no advisory or other comment. It was an expensive repair. I don't have a warranty so paid it myself. Whether you have a claim on your warranty will depend on your policy wording, but I would expect corrosion to be excluded.

If you bought the car within six months you might have a claim against the selling dealer under the Consumer Rights Act 2015, but absent that I fear that fighting about this will be a fruitless source of extra stress for you. Only Range Rovers since 1988

Not that this will be much help, but one of the main reasons I chopped in my 65 plate VSE last summer was being advised - confirmed by my own inspection - of corroded ARB pipes. It’s an expensive repair; that and the year 10 service meant a huge bill within a year, so despite it being a wonderful, trouble free car, I chopped it in. Car had full MD service history and was on a LRAU warranty, which I renewed each year. The trusted MD advised that LR wouldn’t cover the corroded pipes on warranty.

Similar story for me with my otherwise faultless 2017 AB last year. In MD for 7 year service and was advised that ARC pipes were showing signs of corrosion (although not leaking) and was advised they should be replaced within the next 12 months at a cost of circa £2.5k. Also confirmed that warranty won't cover them as due to corrosion. That and soon needing new tyres all round and not being able to extend warranty as would be over 100k this year, tipped the balance for me to trade it in for another Fattie. 2021 D350 Fifty Edition - Carpathian Grey
