Thread: Restricted Performance warning + stalling

Hey guys,

I'm new here, with a 2011 RRV TDV8 Luxury with the 4.4 TDV8.

I THINK this issue of mine has now been solved, but I thought I would post my experience here briefly for archiving and discussion; hopefully it might help others.

> Bought my RRV from ULR Land Rover in Malvern VIC. 72xxxkm, 2011, one owner with FSH, bought from and exclusively serviced at ULR. Bought 2 year Allianz warranty also.
> Upon inspecting the car, a "Low battery, start engine" warning came up on screen. Dealer suggested it was because the car had been sitting and a few people would've opened/closed doors, locked/unlocked etc.
> Drove the car around Melbourne for a couple of days then drove it back to Sydney via the Snowy Mountains (1,200km). Drove like a champ; didn't miss a beat.
> Over those days in Melbourne and on the way home, it still gave the "Low battery, start engine" warning a few times, especially when I had it in "accessory" mode / ignition on, trying to set various radio / navigation / playing around with TV settings.
> Got home, put it on the trickle charger (Ctek MXS 5.0). Charged to green (maintenance mode) fine.
> Started using it to drive to work (gridlock traffic, avg. speed ~10-15km/h).
> 2nd day, doing a low speed turn out of a laneway, the car stalled in D and flashed the battery light. Restarted the car straight away and then it seemed to drive fine till I parked it.
> Drove home fine. Stuck it back on the trickle charger.
> Over the next few days it gave me a "Restricted performance" warning with yellow triangle on 2 separate occasions, but the car still seemed to drive fine, with no discernible loss of power. The warnings were intermittent, with the car behaving perfectly fine in between.
> I tested the battery with multimeter and got 12.5v across the terminals when off, and 14.5-14.6v when on. Loading the alternator up with accessories (blower, cooled seats, stereo, TVs etc.) didn't seem to affect the output.
> Ordered a cheapie OBDII reader from eBay which wouldn't arrive till today

> Drove to work last Friday; it was performing 100%, then on a mild uphill under about 20% throttle (in peak hour traffic) it cut out; "Restricted performance" warning. This time with red triangle. Car cut out completely; rotary gear knob sunk back into the console. Tried restarting multiple times but just got a series of clicks. Gave it about a minute's rest; then managed to fire it up. "RP" warning and red triangle still on; power delivery extremely sluggish, maybe 10-20% power. Limped it about 1km (in stop-start traffic) to a side street where I switched it off for about 2 mins then restarted; car drove 100% fine again like nothing happened.

> Called ULR in Melbourne and told them the situation. Greg from ULR advised we'd start with the battery.

> Went to Battery World, got the battery tested; it was stamped 2016 (practically new) and it has the Jaguar / LR stickers on it. Battery tested well - it was putting out 70-80% output. Alternator also tested fine according to them.
> BW replaced the battery (with me watching closely and cringing as they extracted the ECU and had a hard time taking the battery out without damaging the surrounding bodywork)

> Car now seems to be running perfectly (have driven 160km round the Blue Mountains over the weekend and another 40-odd since).

> ULR are covering the cost of the battery, thankfully (was $599 for a Century-branded Varta battery).

Sorry for the long read. Fingers crossed that has sorted it; but will add any other updates as they are due.

Anyone else experienced the Restricted Performance issues on the 4.4 TDV8 or similar? I did a search and found some other occurrences but mostly with other LR models like Evoque or Disco.

Oh and here's a couple of pics of the beast.






Cheers
Matt

Thanks for sharing mate. Sounds high-maintenance though that you need to plug in every night. I do have the anderson plug fitting so may need to hook it up to mine.

What wheels are you running your Coopers on, with 285 width? Also interested to know how they fare off-road being on a 20" rim, like mine. Know that Cooper don't make bad offroad tyres but I'm wondering what the limitations are given the 20" size and relatively thin profile.

Can't remember what the warning was but I had the battery & alternator checked by RACQ and Battery World .. both saying the alternator was testing OK but but the battery was just in need of a charge. The battery was regularly charged every month overnight on a Ctek (7amp). I did as advised and charged the battery again. It was OK for a couple of days but then wouldn't start the car.

I took it back to the supplier and again it couldn't be faulted so I bought a new one and the other was sent back to the manufacturer for testing. Some 6 weeks later I got a call from the supplier saying that after several tests the battery was found to be faulty. They very kindly refunded the money I had paid for the new battery.

Wow. You do wonder how frequently batteries are found to be faulty like this. Especially ones like ours that are such a large capacity and $$$.

Yep, on my 2011 (and RHD obviously) it lives just at the firewall in front of the passenger. It's tucked in a "cubby" / enclosed area along with the ECU; between the firewall and another panel that separates it from the back of the motor. We had to set the bonnet in service mode. Apparently it was the first L322 that this mob had done, which didn't exactly inspire confidence, but I'd taken cars there before.

If restricted performance returns and DTCs indicate an airflow plausibility condition then the cause may be a sticky secondary turbo isolation valve. An improved valve linkage was introduced late 2011 IIRC to overcome the sticking which can be identified looking down at the valve located at the front left of the engine. The sticking valve is a known cause of a condition that triggers restricted performance on these engines.

Thanks a lot Graeme - helps to know this. I will definitely be referring back to this should the RP warning return. I *DID* get another "Low battery - please start engine" warning the other day while I was vacuuming the car (interestingly the infotainment system was off, but the door lamps were on). Doing a bit of reading myself I did see that someone had discovered that there was a TSB on this and the dealer can adjust the voltage measurement at which the Low battery warning comes on - apparently it is a bit sensitive and comes on even when there's plenty of charge. I'd also read that the battery needs to be "coded" to the car. Maybe I'll ask LR about that (as well as the turbo isolation valve linkage) when the next service is due in Jan.
