Hi a I ma looking for some advice please I have the reduced power warning coming up in the info display but with no MIL
I can get it to reset by turning off and back on again It seems to be related to throttle position but not to how much power I am trying to pull ,making me think its not the fuel filter. I understand this car can have issues with throttle position sensor .Is it possible this is triggering the error. I could do with understanding what the symptoms of the faulty throttle are
Any advice will be appreciated as this is bugging me
If any help its a 2008 TD4 HSE Auto with 108k on it

thanks in advance

Reduced power warning...with no Mother in Law?

I think you will need to get the codes read, to see if there is anything being flagged up. 2005 D3 2.7 Auto
Previously:
2010 MY FL2 TD4e GS - Now gone at 199,500 miles, about 135,000 of them mine.
‘93 Defender 110 200TDi CSW
‘87 Defender 90 4 cyl Petrol
‘83 110 CSW V8 - best ever!
Range Rover 2-door V8 (not sure of year - 4-speed box and vacuum diff switch)
Series III SWB Diesel

When I have had fuel filter problems it has been when extra fuel is required eg going up a long hill and car goes into reduced power mode but can reset when switched off. When was the filter last replaced? 3 x FL1 2 manual + 1 auto
5 x FL2 4 manual + 1 auto
Now Discovery Sport P250 MHEV SE

I am going to try a new fuel filter this weekend The old one is about 2 years old and done around 15k I have to replace if only to eliminate it being the cause
