General JTD (w Reg) overrevving, flashing brake light and glow plugs! ARGH

[navyeye]

Hi there I'm new here and have had a quick search and can't seem to find anything here that answers these questions.

Over the last couple of days I've noticed a few things on my car which all seems to have started when I drove over some snow and heard a knocking noise from under the car at the front.

1. When idling my car sounds like it's ever so slightly revving - I don't know how much by as there is no rev counter. It doesn't do it all the time.

2. The red (what I think is) break light is intermittently flickering - I have looked in the manual and it doesn't really mention this light on the dash board. I'm thinking my front brakes are on their way out? It's flashing really really lightly.

3. When stationary and I pull off there is a faint sort of clunk noise form the engine.

4. Although the car starts fine after about 1 minute the glow plug light flashes on.

Is there anything basic I can check for before I take it to a garage? Could I have knocked something in the snow? The engine coolant is on min so am going to top that up tomorrow but all other fluids seem fine from my limited knowledge.

Thanks!

Any help much appreciated

2. the blinking brake light, you could be low on brake fluid.

Picture 1: Brake light circled red.

The flickering could just be the handbrake switch not making contact properly mine does it, pull the leatherette shroud back and put a brick behind the wheel then release the h/brake on and off see if its rusty like mine.
Glow plugs could just well be that itself, flash for 30 secs ? then you have one or more dead uns . Not really a problem unless its really cold so your lucky we are kust past the cold spot, just put a multi meter on them and see which one is different.
Reving ? dunno really not had that YET possible connector block under the passenger seat ?

I think that should be the white connector block under the passenger parcel shelf or scuttle!

re: the clunking on takeoff- I had the same noise after the recent snow- sounded like exhaust loose or something.
Turned out to be the thin aluminium heatshield just above the exhaust pipe where it turns to run under the car. The deep snow must have bent it, so it was banging against the bodywork or exhaust when accelarating.
Simple to check- get down on the floor, look under and see if it's out of shape- bend it back if it is.
