    Hey all,

    I picked up my 7th Generation 2007 EX ctdi saloon last w/e so just wanted to share my initial thoughts with you all and get some ideas on a few things.

    Wow. What a machine. I am so, so impressed to say the least! So much torque, delivered so quietly and smoothly! All the toys! The most comfy car seat I've ever sat in. I'm looking forward to doing lots & lots of miles in this one...:Happy::OTT::Thumbup::clap:

    So, mine has been really well cared for, with a full history and came with almost every single invoice from new. However, being the perfectionist I am, there's a few jobs that need doing so I'm after some tips please...

    First off, both of the inner tail lights aren't working. I've swapped the bulbs over with new ones last night but still no joy. The reversing, fog & number plate lights all work fine, so there's clearly power to the area. Anyone else had this problem?

    Secondly, there's a noticeable buzz coming from both the front speakers with even moderate levels of bass & volume. Is this common? Is it likely to be the surrounding fittings in the door card or the speakers themselves? Would be handy to know before I start taking things to bits..

    Thirdly, there's a slight groan/drone coming from the steering column, but seemingly only when turning while reversing, mainly on a left lock. There's no squealing, louder noises, vibration or lumpiness, even when on full lock so I'm hoping its not the rack! The level in the reservoir looks fine. The only 2 advisories on the last MOT were for deteriorated rubbers on the lower front suspension arms and track rod end/ball joints so I'm wondering if this could be the cause? I've got a 3 month warranty..

    Finally, I don't have an instruction manual/book pack (apart from the service book), which is a problem given all the toys on board. I will get one from Honda if I have to, but thought I'd ask here on here first.

    As always, I'd really appreciate any ideas anyone has on these things. She's 95% there, so I need to find the remaining 5% ASAP!

    Thanks all

    PS I will post some pics up once she's properly clean...:Smile:

    Sounds like you've picked up a prime specimen right there James, congrats. When I was hunting for my Facelift it took me a long time to find the right one in the right condition.

    I've not once stumbled on this issue, my first port of call would be the fuse box. I don't have the workshop manuals to hand but the fuse layout diagram is on the back of the slide-out cover, you'll find it in the drivers footwell on the right hand side.

    That sounds like electrical interference, you could well have a bad earth somewhere, which could be related to your previous issue. @SpeedyGee is good at troubleshooting electrical issues.

    The compliance bushes on the lower arms are a common replacement part, they tend to last around 60,000 miles. Some choose to upgrade them to "poly bushes" or solid bushes, but of course you're then adding extra stiffness which will translate more into the cabin. I'd be looking at the track rods as the cause of the steering groan personally.

    You can pick up the owners and workshop manuals on eBay without an issue, normally loads floating around, they cost just a few pennies directly from Honda. We unfortunately can't share them on the board because of copyright :police:

    Lastly, keen to see some shots once she's all cleaned up!

    Assuming it's all a stock system, it does sound like an earthing issue somewhere. I'd start by removing head unit (there are instructions on how to do this on the site) and ensure all the plugs are connected properly. It maybe that the last owner went to remove something like an Aux In plugin just before selling car and didn't put everything back together correct.

    If that doesn't fix it then whilst you have the head unit out, try getting a piece of wire, touching one end to the chassis of the head unit and another to a good earth point, see if the humming goes away.

    Many thanks for your reply, all really helpful & useful advice. I will make a start on some of these things this w/e and let you know how I get on.

    Done over 400 miles this week alone, and regularly seeing 58mpg. Amazing!

    Cheers again..

    She sounds fantastic, looking forward to her being added to the garage. What mileage has she done? I agree about the comfortable seats, did almost 400 mile round trip a weeks ago in one go, didnt have a second worth of pain or discomfort.

    I would use your 3 month warranty whilst you can. I agree with DD about the groaning possibly being your track rods, they are easy to replace yourself but why should you when you can get the garage to do it for you. Jack the wheel up, put your hands on 9 and 3 position and rock her back and forth. It should be as solid as a rock, if it flexes at all, the slightest knock, side to side, get them checked out. As they were already advisories from the MOT, chances are they need doing.

    Looks to me like they are all run off the same fuse, but I stand to be corrected. Are you at least getting power to the connector? Have you tested that seperately with a multimeter

    Thanks for this. It is a stock system (with sat nav). I can tackle most straightforward car jobs, but I'm always a bit hesitant with electrics, especially with a system as complex as this. Still, the hourly rate of my nearest dealer is the ultimate incentive to get stuck in, so I will check out the guide on here and give an update next week. As I don't have any books for it, I take it there's some form of security code to enter when I power everything back up again? What would be the best way of obtaining this? Finally, is it possible to connect an MP3 player via this set up or not? I can see there's an Aux button but haven't found a Jack yet...

    Any advice appreciated - thanks!

    Thanks for all this, all really useful info. Unfortunately I haven't got a multimeter, simply because I never needed one with my 6th Generation. But clearly I need to get hold of one! I will have a dig around in the fuse box to see what I can find. There's clearly going to be a lot of them from your description!

    And in answer to your first question, 120k. But honestly feels like half that, which won't come as a surprise. I had to chuckle today when one of my neighbours asked me that question and then did the usual sucking through teeth response when I told him. He drives a purple Nissan Juke. Enough said...

    Also re the track rods being the possible source of the groan, I've just checked the small print of the warranty & predictably enough, if it is this, it's not covered - only the rack is. In any case, the garage is 2 hours away so unless it is the rack, it's going to be a DIY job...

    Truthfully mate, you have come to the right place, a DIY was uploaded a few weeks ago. At 120k, you have nothing to lose by changing them, they are cheap enough anyway even going OEM

    Great, will check this out too - thanks!
