Hello all, new to the forums as a member but have been reading them since i bought "the tank" earlier in the year. I have a Master on a Mascott chassis with the 3.0 litre 160 bhp Nissan engine. I was driving on the motorway in very heavy rain last week. The van in front went through a huge puddle throwing it up on me, then i hit the puddle moments later. It slowed me down quite a bit and i noticed when i put my foot down to accelerate it hesitated for a second or two before pulling as normal. Was close to home and when i left the motorway it was very sluggish to pull away until it hit 3000 rpm.

I was hoping it might just be something water related that would dry out overnight however in the morning when i turned the ignition on it wouldn't rev up. Foot flat on the floor and nothing happened for about 10 seconds before it revved as normal. The lack of power was still present below 3000 and hit and miss above that.

Over the past few days its stayed the same apart from one day it bizarrely seemed to have more power and today its very poor. Only 35 mph foot on the floor going up a nearby hill.

Has anybody else experienced similar or have an idea what it may be?

It has done 1080000 and the serv light is on permanently (it has been since i got it) and the coil light stays on when starting from cold until the engine is turned off then back on again.

Thanks in advance for any advice

Could be worth checking the intake pipework for retained water especially the intercooler and any pipework with dips. I tipped about 1 pint out the I/C from my flood damaged Scenic.

Re: Renault Master 3.0 160 loss of power after driving through water

Hi thanks for your replies. Got to the bottom of it today. Aitflow sensor was faulty, it looks like the water had caused it to malfunction. When it was taken off the little filament inside had started to corrode. A hefty £190 for the part but fortunately a 5 minute job to fit. Back on the road again now!
