My 05 S/C show constant low coolant level. The level in the expansion tank is correct, and the LR guys reackon its a faulty sensor in the tank which needs a whole tank replacement. Anyone had anything similar?

If the tank is actually full, then it sounds like the dealer has it right. I don't remember that ever being reported on here but that's not to say such a thing wouldn't happen

ok, it's soon going in 4 a service anyway, should be sorted then. Cheers!

I had this - the float in the tank is absorbing water and sinks and sets off the low coolant warning. This is a warranty job and has happened to many. 2005 Zambezi TDV6 - Gone but not forgotten

There is actually a TSB issued for this (see the NA version below, the one in Europe may or may not be different.) Problem is, for a while dealers in the US were replacing faulty expansion tanks with more faulty tanks! There must have been a big batch of them around. Make sure your dealer is aware of the TSB, as you can see there is a specific manufacture date or code on the "good" tanks they need to check before installing. I am sure they are aware of that by now, but this is Land Rover and you never know...

Quote:

TSB# LS303-006

SECTION: 303-03
"Low Coolant Level" Message or Warning Lamp Illuminated
AFFECTED VEHICLE RANGE:
Range Rover Sport (LS) VIN: 6A900129 to 6A929342
CONDITION SUMMARY:
"LOW COOLANT LEVEL" MESSAGE OR WARNING LAMP ILLUMINATED
Situation: A customer may report that the "Low Coolant" amber warning lamp is illuminated or a "Low Coolant Level" message is displayed in the Message Center when the engine coolant expansion tank volume is within recommended levels.
The coolant level float in the expansion tank can absorb coolant causing the float to sink. The warning lamp and message will display when the float sinks below the low level sensor trigger point.
Action: Should a customer express a concern related to the above condition, within the specified VIN range, refer to the Repair Procedure detailed in this bulletin.
PARTS:
NOTE: The current expansion tank part PCF500015 may be used only if the sticker on the side of the part has a date of 31-10-05 (DD-MM-YY) or later. A newer part PCF500090 may be used when available.
PCF500015..............Coolant expansion tank (dated 31-10-05 or later) Qty 1
PCF500090..............Coolant expansion tank Qty 1

 

Thanks umbertob.

I will certainly forward a copy of this TSB to the guys at Land Rover... . Malaysia Boleh!

Seems more widespread than I thought... what do I know, I drive a BMW!

Yep, had this after the dealer fitted the FBH which required draining the coolant down. I thought they hadn't fully refilled the reservoir and complained that they had had the car for 3 days and should have run it enough to find out if there were air locks. Turned out to be the sensor was faulty too. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Yep, mine has had that and is in at the moment getting it sorted. Also having some other minor work done.......namely the entire drivline being replaced  RRS TDV6 Bluetooth, VR, Roof

I thought it was just me. Thanks for the responses. I will go stand in line for a back ordered part once again. :lol:

Welcome Baxter!

Don't worry, there are very few problems that are "one offs", so if you do get a prob, just check out a few of the forums and you will more than likely find a solution! RRS TDV6 Bluetooth, VR, Roof

Parts appear to be off backorder in UK now - booked in for Thursday... Also having OSR door seal replaced on pillar - adhesive drying out and peeled away...

I just had mine done £155.00 plus VAT from my local Stealer.
