Hi guys,

 

My 300 failed its MOT today. Im in need of advice for a few issues

 

1. Foglight not working (j-spec). Which light is normally used for the foglight? it may help with finding the wiring. The switch is installed on the centre console just to the left of the clock if that helps.

 

2. 4 new tyres (standard wheels). Ive been roughly quoted £358 for some cheap tyres fitted (kumho i believe)- is this about right? i'm only after cheapish ones atm.

 

Other than that, it also failed on a split steering gaitor (not too bad) and the headlights arent working properly. Its the connection not the bulbs as you can move the wires about and they flicker on and off! very annoying as i cant see whats going on due to where the connector is.

 

Thats it! Well i say "thats it" but i was hoping it was just the rears that were illegal!

 

Ive just added some EBC grooved fronts so i may actually be able to stop like a car not a oil tanker!

 

Any help would be great folks cheers

Hi Ad,

 

That's not too bad at all! Consider yourself lucky! My answers are in your original message below:

Fog lights = H3 bulbs. The side light (also located in the fog light enclosure) = W5W also known as 501 capless bulbs.

 

2. 4 new tyres (standard wheels). Ive been roughly quoted £358 for some cheap tyres fitted (kumho i believe)- is this about right? i'm only after cheapish ones atm.

That's about right. Have just done a quick check on some of the online tyre resellers I use and all the "budget" type tyres come out at between £85 and £95 per tyre (excl. fitting). FYI - tyre size for J-spec car is 4x 225/50R16

 

Other than that, it also failed on a split steering gaitor (not too bad) and the headlights arent working properly. Its the connection not the bulbs as you can move the wires about and they flicker on and off! very annoying as i cant see whats going on due to where the connector is.

Could well be a break in the wiring loom leading up to the connector. Both the dip beam and main beam bulbs are connected directly into the connector blocks so if wiggling them about the connector should not loose connection with the bulbs. If they do then it could be down to corrosion inside the connectors (just clean using electrical connector cleaner and a small screwdriver) or a break in the wire (not so easy to resolve apart from replacing the affected lenght of wiring loom).

Brake performance on a standard car should not be like an oil tanker! If so then the calipers could be seized or your brake pad/disc combination isn't ideal. You'd be surprised how much you can change the braking performance by just changing brake pads.

 

Any help would be great folks cheers

I hope the above has been useful in some way.

 

Good luck!

Hi Dan,

 

In answer to your answers,

1. Its the rear foglight. As its a j spec car i believe that they need a rear one fitting on entering the UK? I had one installed on my EF8 CRX when it came in to the country from japan. Anyway, they cant find it, or see it working or something (really should pick a garage closer to my work lol). May need to inspect it myself.

 

2. The tyres didnt sound too bad, cheers.

 

3. yeah, the headlights are a PITA but im hoping they'll add a minimal amount to fix this to my bill.

 

4. the term "oil tanker" was an exaggeration, the brakes were ok before, but compared to other cars ive driven they seem a bit shoddy and ive driven more than one 300. i may check the calipers but that wouldve been flagged up in the MOT? Maybe if they just check the brakes for "bite" rather than strength if you know what i mean

 

cheers

also, r.e. the tyres query, arent the fronts narrower than the rears? or have i missed something here?

rear fog lights on imports usually wired into one of the reversing lights, mine is the off side although i guess it could be any, also im guessing you could get part worn tyres from one of the breakers on here for almost nothing for stock wheels, might be worth a look.

NO. That is only the case on a UK-spec car (front = 225/50R16 rear = 245/45R16). A JDM car has 225/50R16 all-round.

Er, ok -just checked - my car has 225/50 R16's on the front and 245/45 R16's on the rear but its definately a j-spec! Will 225/50 R16 still go on? they're working out much cheaper than the wider ones. Im confused!!

ok - found out that the previous owner (RussT) put uk rear wheels on! so ive ordered the correct sizes.

 

cheers for your help guys

possibly your car has been fitted with Uk spec wheels ( a common mod ) although you could tell by looking at the side wall does it look like its oversized for the rim width compared to the front tyre, if so then just the uk tyre spec has been used , you can go back to J spec easily and cheaper
